New Debis Clearing

Vessel Design

Alan C. McClure Associates (ACMA) completed its contract from the

Guadalupe-Blanco River Authority (GBRA) to design and supervise the construction of a 32-ft. barge that will remove debris from the Blanco and

Guadalupe rivers and their tributaries as they flow through south and southeast

Texas. After establishing the capabilities that would be required to operate in this specialized environment. ACMA devel- oped the conceptual design, recom- mended equipment and propulsion sys- tems. developed bid specifications, dis- tributed specifications to shipyards for bids, evaluated bid packages, oversaw construction and provided owner's rep- resentation throughout the project. "Although this was basically a 'soup to nuts' assignment," said ACMA

President. Scott McClure, "I'm not aware of any other vessel quite like this one. Of course, the ACMA team always enjoys a new and challenging assign- ment and given our extensive analytical and shipyard experience, this is exactly the kind of assignment we specialize in."

Dubbed Miss Guadalupe II, the

GBRA's newest vessel meets the chal- lenge of operating in very shallow water, while still maintaining its ability to fit under low-level bridges along the water- ways. To accommodate a drive-on front- loader that's positioned on the deck to remove different types of debris from the rivers, the craft's beam has been specifically designed to create a very stable environment. And, with its

Thrustmaster hydraulic thrusters, the vessel is highly maneuverable. This ves- sel also has the advantage of being small enough to be truckable to any number of marine locations.

The Miss Guadalupe II was fabricated and constructed at Bollinger Houston

L.L.C.. a subsidiary of Bollinger

Shipyards, Inc. "This was a great project for our Houston yard," said Robert

Socha, executive vice president market- ing and sales of Bollinger. "The facility is noted for its inland and offshore ves- sel services and this project provided the industry with another example of our

Houston yard's many marine talents."

Larry T. Rigdon, President and Chief

Executive Officer of Rigdon Marine, announced that the third of its 10 platform supply vessels — MV Royal — was christened and delivered for service. Royal was immedi- ately deployed to begin work in the Gulf of

Mexico.

Mrs. Mathilde Currence, the wife of

Mobile, Alabama. Royal joins the company's two other vessels, the Bourbon and the

Orleans, which are also working in the Gulf of

Mexico. "We are extremely pleased that drilling and seismic companies with opera- tions in the Gulf of Mexico have vetted our vessels as being the most cost effective and operationally efficient ships available today," said Rigdon. "Their acknowledgement of our vessel's increased payloads and speed with reduced fuel consumption has come in the form of contracts to employ these technolog- ically advanced ships." The Guido Perla and

Associates designed (GPA 640) vessels are equipped with two stern-mounted Steerprop

SP 20 azimuthing Z-drive units that are driven by two Alconza 2,100-hp variable-frequency

AC electric motors, which provide the main propulsion. A further enhancement to the diesel- electric drives is the advanced dynam- ic positioning system and vessel management system from Alstom Power Conversion.
